19. It is narrated from him (narrator of the Hadith above) from Muhammad ibn Ali from Mufaddal ibn Salih al-‘Asadi from Muhammad ibn Harun from Abu ‘Abdillah عليه السلام who has said the following: “Whenever anyone of you prays and does not mention the Holy Prophet and his family in his prayer, his prayer will be taken to a direction other than that toward paradise. The Messenger of Allah has said, ‘If a person before whom my name is mentioned does not ask from Allah al-Salat (favors) for me, he will enter the fire and Allah will move him away.’ He also has said, ‘If a person, before whom my name is mentioned, forgets to ask from Allah al-Salat for me, he will get lost on the way of paradise.’”
